Method of Making Novelty Ice Cubes

1. Field of the Invention

The present invention relates to an ice cube. More particularly, the present invention relates to a novelty ice cube.

2. Description of the Prior Art

Numerous innovations for ice have been provided in the prior art that will be described. Even though these innovations may be suitable for the specific individual purposes to which they address, however, they differ from the present invention.

FOR EXAMPLE, U.S. Pat. No. 4,021,583 to Arden teaches a fruit-flavored quiescently frozen confection which is high in total fruit solids content and which has increased resistance to melting and increased protection against stickiness in storage. The high concentration of fruit is obtained by using pureed fruit.

ANOTHER EXAMPLE, U.S. Pat. No. 5,077,075 to Wade teaches a fruit juice mix suitable for hard pack product made essentially from natural ingredients containing at least one fruit juice source in association with about 0.05 to 1.5 percent by weight of various stabilizers and preferably 0.30 to 0.60 percent xanthan gum based upon the total weight of the mix. An amount of water and other ingredients such that the blend has a brix value of greater than about 10 to about 35 and for more desirable results of 20 to 30 and preferably 20 to 25. No refined sugar or corn sweetener is added in or to the blend. Moreover, the juice mix can be frozen to form a hard pack material that can be stored at lower temperature, usually minus 18 degrees C. and lower for days and then be warmed to minus 5 to minus 10 degrees C. and be scooped out to be served and eaten without the appearance of being too icy, coarse, crumbly or gummy but exhibits a smooth, fine creamy texture and superior melt characteristics relative to soft pack.

STILL ANOTHER EXAMPLE, U.S. Pat. No. 5,394,705 to Torii et al. teaches a flavored ice manufacturing method for manufacturing flavored ice with a taste and smell possessing a uniform color or is colorless, which comprises a block ice manufacturing process; a crushing process for crushing this manufactured block ice into ice particles; and a sorting process for sorting these crushed ice particles into flavored ice of a predetermined particle diameter. In the sorting process, the ice particles are sorted into flavored ice of a predetermined particle diameter while spraying a dry-cooling fluid of 0 degrees C. or less onto the ice particles. As a result, a dry-cooling liquid is sprayed around the periphery of these ice particles, and thus the surface temperature of these ice particles can be maintained at a low temperature, and the water component existing around the periphery can be blown away. In this manner, adhesion of water and minute particles to the surface of the ice particles, as well as adhesion of neighboring ice particles is prevented. Consequently, the taste sensation of the flavored ice as well as the separation workability of the ice particles can be improved. In addition, the present invention provides flavored ice with an improved taste possessing a particle size within a predetermined range, which is difficult to melt, and in which there is no adhesion.

FINALLY, YET ANOTHER EXAMPLE, U.S. Pat. No. 5,603,219 to Kolb teaches an ice cell for the cooling of drinks that comprises a closed hollow body filled with a freezable liquid. The hollow body is made at least partially of a transparent material and has least one insert freely movable therein. The insert can have a printing thereon, be colored or marked in any desired manner, e.g., to identify the drink contained in the glass.

It is apparent that numerous innovations for ice have been provided in the prior art that are adapted to be used. Furthermore, even though these innovations may be suitable for the specific individual purposes to which they address, however, they would not be suitable for the purposes of the present invention as heretofore described.

ACCORDINGLY, AN OBJECT of the present invention is to provide a novelty ice cube that avoids the disadvantages of the prior art.

ANOTHER OBJECT of the present invention is to provide a novelty ice cube that is simple and inexpensive to manufacture.

STILL ANOTHER OBJECT of the present invention is to provide a novelty ice cube that is simple to use.

BRIEFLY STATED, YET ANOTHER OBJECT of the present invention is to provide a method of making novelty ice cubes that change color which includes the steps of: pouring water into a first ice cube tray to form a poured first solution; freezing the poured first solution to form a frozen first solution; removing the frozen first solution from the first ice cube tray to form clear ice cubes; adding a food dye to citric acid to form a second solution; mixing the second solution to form a mixed second solution; pouring a thin layer of the mixed second solution into a second ice cube tray to form a poured thin layer; freezing the poured thin layer to form a frozen thin layer; wetting the frozen thin layer to form a wetted thin layer; placing a clear ice cube of the clear ice cubes onto each wetted thin layer to form a combination; pouring an additional amount of the mixed second solution onto the combination, until a thin layer of the mixed second solution covers the exposed portion of the clear ice cubes to form together with the frozen thin layer a thin layer encasement that completely encases the clear ice cubes and forms with the clear ice cubes an encased combination; freezing the encased combination to from a frozen combination; removing the frozen combination from the second ice cube tray to form colored and flavored ice cubes; putting the colored and flavored ice cubes into a drink; and causing the thin layer encasement to melt and become substantially clear.

The novel features which are considered characteristic of the present invention are set forth in the appended claims.

STEP 14: Cause the thin layer encasement 151 to melt and become substantially clear, by virtue of the drink 144 diluting the citric acid (H.sub.3 C.sub.6 H.sub.5 O.sub.7 H.sub.2 O) 112 which substantially decolors the food dye (C.sub.20 H.sub.6 O.sub.5 I.sub.4 Na.sub.2) 130.

5 ml of water (H.sub.2 O) 114 was poured into the first ice cube tray 136 to form the poured first solution 116. The poured first solution 116 was frozen to form the frozen first solution 117. The frozen first solution 117 was removed from the first ice cube tray 136 to form the clear ice cubes 119. The food dye (C.sub.20 H.sub.6 O.sub.5 I.sub.4 Na.sub.2) 130 was added to the citric acid (H.sub.3 C.sub.6 H.sub.5 O.sub.7 H.sub.2 O) 112 to form the second solution 132. The second solution 132 was mixed to form the mixed second solution 134. A thin layer 135 of the mixed second solution 134 was poured into the second ice cube tray 139 to form the poured thin layer 138. The poured thin layer 138 was frozen to form the frozen thin layer 140. The frozen thin layer 140 was wetted to form the wetted thin layer 143. A clear ice cube of the clear ice cubes 119 was placed onto each wetted thin layer 143 to form the combination 147. An additional amount 145 of the mixed second solution 134 was poured onto the combination 147, until the thin layer 149 of the mixed second solution 134 covered the exposed portion 159 of the clear ice cubes 119 and formed together with the frozen thin layer 140 the thin layer encasement 151 that completely encases the clear ice cubes 119, which forms with clear ice cubes 119 the encased combination 155. The encased combination 155 was frozen to from the frozen combination 153. The frozen combination 153 was removed from the second ice cube tray 139 to form the colored and flavored ice cubes 142. The colored and flavored ice cubes 142 were put into the drink 144. The thin layer encasement 151 was caused to melt and become substantially clear.
